San Diego Padres at Philadelphia Phillies (2:37 p.m. ET, FS1)

Phillies lead series 3-1

Padres starter: Yu Darvish

Phillies starter: Zack Wheeler

Starting lineups:

PADRES

TBD

PHILLIES

TBD

What to watch for: Padres manager Bob Melvin will need to ride Game 5 starter Yu Darvish for as long as he can in an ace showdown with Philadelphia's Zack Wheeler after everything San Diego tried on the mound backfired in Game 4. In fact, both bullpens are taxed after the teams used a combined 13 pitchers on Saturday.

Meanwhile, the Phillies are swinging their bats so well right now, they should be able to play loose and easy knowing they have a two-game lead in the series and Aaron Nola waiting in the wings for Game 6 -- if needed.

Almost all of Philly's bats have contributed so far this series, and there's little reason to think that will end Sunday. That's why it is all on Darvish to save the Padres' season. -- Jesse Rogers

Our picks

Phillies 3, Padres 2: Darvish will pitch his heart out but Philadelphia has that destiny look -- at least to win the NL pennant. It will survive a tight, low-scoring affair -- the exact opposite of Game 4 -- and win the series with a tight win on Sunday. -- Rogers

Phillies 5, Padres 2: The Phillies are 4-0 at home in the postseason and they look like they're ready to pop some champagne. Wheeler has been outstanding over his three playoff starts and top relievers Jose Alvarado and Seranthony Dominguez didn't have to pitch in Game 4 after a little extra workload in Game 3 (a combined 61 pitches), so everything is lining up for a boisterous celebration at Citizens Bank Park. -- David Schoenfield

Houston Astros at New York Yankees (7:07 p.m. ET, TBS)

Astros lead series 3-0

Astros starter: Lance McCullers Jr.

Yankees starter: Nestor Cortes

Starting lineups:

ASTROS

TBD

YANKEES

TBD

What to watch for: The Yankees will need to look to the 2004 Red Sox as a source of inspiration as New York faces a 3-0 deficit in the ALCS against the Astros. Houston has cruised through the series, looking like the better team in every aspect of the game, highlighted by strong performances from starting pitchers Justin Verlander, Framber Valdez and Cristian Javier. McCullers will have the chance to close things out on Sunday against a Yankees lineup that looked totally lifeless in Games 2 and 3.

Houston will need more of the same to punch a ticket to the World Series: strong performances up and down the lineup. The Yankees will need a season-extending outing from Cortes, who has been their most consistent starter all year. New York's lineup will need to wake up, starting with Aaron Judge, who has had an awful postseason, hitting .156/.182/.344. -- Joon Lee

Our picks

Astros 4, Yankees 2: The Yankees' season ends on a disappointing and uncompetitive note as the Astros continue their postseason undefeated streak off a solid all-around performance from the offense and a strong start from McCullers. -- Lee

Astros 7, Yankees 2: It's a not-very-analytical take, but the Yankees' body language was very zombie-like on Saturday. They look done. -- Bradford Doolittle

Astros 2, Yankees 1: Not even Cortes on full rest can stop the juggernaut that is Houston, with McCullers Jr. the latest to silence New York's bats. -- Jeff Passan
